Pupil monitor

Pupil monitor

You can see how the areas of my visible right eye (during treatment, because of the loss of central vision in my left eye, the ‘tracking monitor’ was watching my right eye instead of my left eye that has the tumor) are marked on the monitor.

Should I lose the flashing light that I must train my eye at to be certain the proton beam is directed correctly, the doctors will immediately put a stop to the beam so as to not cause additional damage to my eye. It’s only the tumor we want, not the whole eye.

A patient not being able to maintain his aimed eye line during the treatment increases his chances of losing the eye. Fully 1/3 of proton radiation treatment patients have to have the treated eye removed. This is usually due to the tumor killing the eye before the radiation kills the tumor, I believe. Hey, staring at a flashing light at the edge of your vision for 90 seconds seems easy at first…. but it isn’t.

Two monitors are used

The proton radiation treatments are monitored from a short distance. No one wants to be in the same room as the patient (for safety and health reasons) during the actual radiation treatment.

The patient (me) is watched for panic in the left monitor (as well I have a panic button in my hand once I am positioned into place and the mask is set) and in the right monitor my right pupil is seen enlarged. Should my vision move outside of the allowed areas, as seen from the marks on the pupil monitor, the treatment will be immediately stopped so as not to send the proton beams to an area that is not the tumor.

Watched via monitor

It’s much harder than it looks…. Christine (from the BC Cancer Agency) Has to make sure that I’m correctly positioned while in the chair. Measurements are to the 1/1000 of a milimeter, that’s how exact the proton radiation is directed at the tumor behind my left eye.
